In the front and rear circumferential walls 6a and 6c and the intermediate circumferential wall 6b, The dimension L3 between the base end 6d and the free end 6e is the same. It is preferable that dimension L3 exists in the range of 1-2 cm. If it is smaller than 1 cm, the excrement falls over the circumferential wall 6, and the leakage preventing function of the circumferential wall 6 becomes insufficient. If it is larger than 2 cm, when the circumferential wall 6 falls to the inside of the panel 1 and covers the upper surface of the bottom part 5, the exposed area of the bottom part 5 becomes small and the liquid absorption property of the core 4 is reduced. There is something that hinders.

5 is a partially broken plan view when the panel 1 is attached to the diaper cover 30. The diaper cover 30 has an hourglass shape as a laminate of a surface sheet 31 made of a plastic film and a back sheet 32 made of a nonwoven fabric. The cover 30 has front and rear trunk circumference regions 40 and 42 in the longitudinal direction and a crotch region 41 positioned between these front and rear trunk circumference regions 40 and 42.

An elastic member 33 extending in the longitudinal direction is attached to at least one inner surface of the front and back sheets 31 and 32 in an extended state at the side edge portion of the crotch region 41. The panel 1 is detachably attached to the inner surface of the cover 30 from the rear torso region 42 through the crotch region 41 via an adhesive (not shown). The panel 1 can appropriately change its attachment position and can be used for urine or physiological use by the attachment position.

The cover 30 has a tape fastener 34 at both edges of the rear circumferential region 42, and the panel 1 and the cover 30 as in the case of wearing a conventional disposable diaper using the fastener 34. By wearing the assembly with), the anus of the wearer can be positioned almost in the center of the upper opening 7 of the panel 1.

When the panel 1 is used in this way, the excrement is not excreted into the upper opening 7 and does not contaminate the cover 30. When discarding feces, only the small panel 1 is to be grasped without catching the large cover 30, thereby making it easier to discard. When the rear circumferential wall 6c having a sharper shape than the front circumferential wall 6a is positioned in the crotch region 41, the rear end 22 is stored between the crotch of the wearer when the cover 30 is worn, and the panel 1 There is no discomfort by using. A large amount of excretion can be received and absorbed inside the front wall 6a on which the core 4 is disposed, which is blunter than the rear wall 6c. In the panel 1, the dimension L3 from the base end 6d of the circumferential wall 6 to the free end 6e is approximately the same as the front and back circumferential walls 6a and 6c and the intermediate circumferential wall 6b, and the dimension L3 is 1 to 2. Since it is in the range of cm, even if these peripheral walls 6a, 6b, 6c fall down, they only cover the periphery of the bottom part 5 and prevent the absorption of the body fluid in the bottom part 5 of the panel 1. There is no work.

6 and 7 are perspective views of pads having a different form from those of FIG. 1, and a cross-sectional view taken along the line C-C in FIG. 6. The panel 1 has a core 4 interposed between the top sheet 2 and the back sheet 3, and has a front end portion 20, a rear end portion 22, and a front and rear end portion 22 in the longitudinal direction. In the point which has the intermediate part 21 located in between, and has the front-back main wall 6a, 6c located in the front-back end part 20, 22, and the intermediate main wall 6b located in the middle part 21, FIG. Same as panel (1).

In the bottom part 5 of the panel 1, the core 4 gradually rises upwards of the panel 1 toward the center line Y, and forms the peak part 5b extended in the longitudinal direction. When the panel 1 in the figure is used for physiological use, the ridge 5b can be brought into contact with and close to the female phase, which is excellent for absorption of menstrual blood. Acupuncture points that penetrate the periphery of the bottom part 5 of the panel 1 can prevent leakage to the outside of the circumferential wall 6 because the circumferential wall 6 serves as a barrier.

As the top sheet 2, a hydrophobic sheet such as a nonwoven fabric or a porous plastic film, preferably a hydrophobic sheet is used as the liquid-permeable sheet. As the back sheet 3, an impervious plastic film, a laminate sheet of the plastic film and a hydrophobic nonwoven fabric, and preferably an air impermeable sheet is used.

As the nonwoven fabric, nonwoven fabrics such as spunlace, needle punch, melt blow, thermal bond, span bond, and chemical bond can be used. The basis weight is 15 to 80 g / m ² , preferably 20 to 60 g / m ² . As the constituent fibers of the nonwoven fabric, polyolefin-based, polyester-based, polyamide-based fibers, polyethylene / polypropylene, or polyester composite fibers can be used.

The core 4 is mainly compressed with a mixture of flat pulp and superabsorbent hydrogel particles, and the whole thereof is covered with a water-permeable sheet such as tissue paper. For fixing the sheets 2 and 3 and for attaching the elastic member 8, an adhesive such as a hot melt adhesive, an adhesive, or a technique of thermal welding can be used.

The present invention can also be used by directly attaching to the wearing shorts and pants with only the processed article without using the diaper cover 30.

According to the bodily fluid treatment article according to the present invention, it can be applied to both urine, feces or menstruation according to the attachment position of the article, and these excrement or acupuncture points received inside the article from the opening of the article penetrates the top sheet and passes through the core. Is absorbed in.

The article penetrates from the periphery of the bottom of the panel since the bottom and the front and rear circumferences form pockets that open toward the longitudinally inner side of the panel, and the bottom and middle circumference walls form pockets that open toward the widthwise inner side of the panel. It has a leakage prevention function that prevents excretion or acupuncture points.
